Electronic Assembly has announced the DOGS102 graphic displays, which enhances the company's DOG series of full-graphic displays. Their size, 39x42mm is compatible with any flush-mounting box and makes them suitable for building installation applications. They are also suitable for 19inch racks and can be integrated in the front panels of devices measuring 1U in height.
The displays have a resolution of 102x64pixels. LCD supertwist technology ensures good contrast. According to the company, several variants are available and differ in their LED background illumination, which includes white, amber, and green or red. A variant with a white, non-illuminated background is also available. The LED elements have a service life of up to 100,000h of operation.
A 2.5 to 3.3V power supply is required to operate the displays. This, combined with their power consumption of 250µA, make the displays suitable for use in battery-powered devices.
An UC1701 graphics controller is already integrated in addition to the screen memory. The units communicate via a four-wire SPI interface. Eight lines of 17 characters in normal type or four lines of 12 characters in large type can be displayed. A USB test board for Windows PCs, an analogue touch panel, and a fitting zero insertion force connector are likewise available.
The contrast is controlled by software and is set once only, claims the company. The display then maintains this setting across the operating temperature range of -20 to +70°C by way of an integrated temperature compensation facility. Elaborate mechanical assembly is not required, since the displays are soldered directly to the circuit board, says the company.
